The Urth 58mm Circular Polarizing (CPL) + ND64 Lens Filter (Plus+) is a high-quality lens filter specifically designed for photographers and videographers looking to optimize their shots. This filter combines the properties of a circular polarizing filter with an ND64 filter, offering a wide range of creative possibilities. The circular polarizing filter reduces reflections and enhances color saturation, which is particularly beneficial for capturing images of water surfaces or in nature. The ND64 filter, on the other hand, decreases the amount of light entering the camera, allowing for longer exposure times or a wider aperture without compromising image quality. With a diameter of 58 millimeters, this screw-on filter is easy to mount and fits a variety of lenses. Using this filter can help improve image quality and expand creative options in photography and videography.
